Before the introduction of L296, which realizes the step down configuration, this function was implemented with discrete power components driven be integrated PWM regulator circuits (giving a maximum outputcurrent of 300 to 400mA)or with hybrid circuits.Bothof thesesolutionsarecharacterizedby a low efficiency of the power transistor. For this reason it is generallynecessary to operateat frequen...
The development of hybrid systems of renewable electricity generation with or without hydrogen storage, particularly in isolated sites, whose aim is to ensure power supply without interruption and minimize the environmental hazard, represents a viable and sustainable solution. It is in this context that this work was undertaken, it relates to the study and the dimensioning of a hybrid autonomou...
Using the renewable energy is the better option to supply demined in the standalone area. World’s most fast-growing renewable energy resource is the wind energy. One of the main disadvantages of this system, however, is that naturally variable wind speed causes power fluctuation problems at the load side. Besides, long-term storage of power generated by wind turbines is considered as a limitati...
One of the greatest challenges of renewable resources is unpredictable nature of these resources. Nevertheless use of fossil-renewable integrated hybrid system, which uses some renewable resources rather than a single source, for the supply of power, is the most affordable and the most reliable method. In this study by use of analytical programming approach and 2012 base year statistics, produc...
Abstract:This paper presents the planning of an optimal Energy Management System (EMS) supported by a fuzzy logic Controller (FLC) for a residential grid-connected micro grid with hybrid renewable generation (Wind & Photo Voltaic) and storage system. Modelling hybrid system includes Renewable Energy Sources given at intermittent supply conditions and dynamic energy demand, and to make conceptua...
-The paper presents the viability of domestic standalone Photovoltaic (PV) hybrid systems in Indian rural areas. The standalone supply system powered by single nonconventional sources such as solar, wind turbines or tidal face unpopularity due to the inconsistency and undependable variance in their source throughout the day/year. The above drawbacks can be addressed by combining minimum of two ...
The nonlinear load such as UPS, fan controller, mobile charger is distorting the supply current waveform. This current harmonics derates the power system equipment. To avoid this current harmonics, filters namely passive filter / active filter /hybrid filters are introduced in the supply line. In this paper the overall view of the performance of the various filters are studied and the performan...
A very low power consumption viterbi decoder has been developed by low supply voltage and 0.15 μm CMOS process technology. Significant power reduction can be achieved by modifying the design and implementation of viterbi decoder using conventional techniques traceback and Register Exchange to Hybrid Register Exchange Method (HREM), Minimum Transition Register Exchange Method (MTREM), Minimum Tr...
